Size of the Triceratops

Triceratops are a genus of large dinosaurs that walked the earth over 60 million years ago. Their fossilized bones have been discovered across North America, and they are most notably recognized by their three-horned, bony-frilled skulls. At least two unique species of Triceratops have been identified so far, both with similar features. Living within the hunting grounds of the fearsome Tyrannosaurus, the size of the Triceratops was undoubtedly important for their survival.

The average adult Triceratops could grow to be nearly ten feet tall and 30 feet long, with three pointed horns that would extend almost four feet in front of their face. That’s about the same height as an average African elephant, but twice as long. The skull of an adult Triceratops could reach about one-third of the dinosaur’s total body length, setting a record as one of the largest skulls among land animals to ever be revealed. Based on the fossils left behind, scientists believe that this dinosaur weighed anywhere from 14,000 to 25,000 pounds.

Just like other animals that are alive today, Triceratops grew in size as they matured. It is believed that they hatched from eggs, and during their development, the two horns above their eyes would change to become formidable weapons, if threatened. Young Triceratops had horns that were short and curved backwards, while sexually mature Triceratops appear to have longer horns that extend downwards. The presence of blood vessels in their horns suggests that their horns may have been used for social purposes as well as defense. If Triceratops were still alive today, they would be the largest land animals on Earth.
